METAL HOSE-COUPLING AND WASHER.

SPECIFICATION forming part of Letters Patent No. 682,873, datedseptember 17, 1901.

Application filed June 23, 1900.

To all whom t may concern:

Beit known thatI, FRANCISCO D.Jov, a citi= zen of the United 4States,residing near Glendora, in the county of Los Angeles and State ofCalifornia, have invented a new and Im proved Hose-Coupling, of whichthe following is a specification.

My invention is an improvement in that class of hose-couplings employedfor connecting different sections of hose with each other or with ahydrant or tank to or from which liquids are designed to tlow.

The improvement relates particularly to the construction of the couplingproper and the Washer used therewith, whereby when the washer is placedin due position it will retain it under all ordinary conditions of useand disuse until intentionally removed. The construction and combinationof parts whereby this object is attained are illustrated in theaccompanying drawings, in which- Figure I is a plan View of my improvedhosecoupling with the Washer in position, a portion being broken away toshow the arrangement of the Washer. Fig. 2 is a side View of thecoupling-section without the Washer. Fig. 3 is a plan view of theWasher. Fig. 4 is a side View of the section with the Washer in place.Fig. 5 is a part plan and part sectional View of a complete coupling inwhich my invention is applied.

The metal coupling-section D has the same form as one which has longbeen in general use, but differs therefrom in that arc slots A areprovided in its side walls at opposite sides to receive the washer, asshown in Figs. 1, 4, and 5. The Washer has a circular opening C (seeFig. 3) and lateral extensions B at opposite sides. The circular body ofthe washer is adapted to iit in the hose-coupling section D, and theextensions or wings B project through and beyond the slots A in saidbody. By this means the Washer is securely held in place during all'ordinary conditions of use, and yet, owing to its flexibility, it may bereadily detached and a new one substituted when required. It will benoted that the extremities of the extensions or wings B are curvedconcentrically with the hose-section I). This means for applying andsecuring seria No. 21,395. (No model.)

the Washer constitute an improvement upon those hose-couplings in whichthe washer is held in a shallow groove or by some form of corrugationwithin the hose-coupling section and which have proved unsatisfactoryand unreliable, especially when the Washers have become slightly worn orshrunken.

In Fig. 5 I illustrate the Washer C asyapplied in a complete coupling,the letters X and Y indicating tubes to which elastic hose is secured inpractice, the same being provided with circumferential ribs orcorrugations and connected by the section D in a well-'known manner.Thus the said section is screwed on the threaded portion or tenon ofpart Y, its ared end abutting the collar y of the latter and the part Xhaving a rotatable attachment to section D. The washer C is pressed bythe tenon of Yagainst the head of partX when the parts are screwedtogether, thus forming a tight joint.

What I claim isp l 1. A hose-coupling section of the class describedcomprising the section proper having lateral slots and awasher havinglateral extensions adaptedfto lit in said slots, substantially as shownand described.

2. The improved hose coupling section formed of a cylindrical bodyhaving lateral slots extending parallel to its end portions,substantially as shown and described.

3. The combination, with a hose-coupling 4section of the class describedhaving lateral sockets, of a washer having a central open; ing andlateral extensions or wings adapted to enter said sockets and therebyhold the washer in place, substantially as shown and described.

` 4. The washer for the hose-coupling sec-- tion, the same having anannular body and opposite lateral extensions or wings, substantially asshown and described.

In testimony whereof I have signed my name to this specification in thepresence of
